Hello,

for my Java course as a project we were to design a program that a sales associate would use to enter customer information, lookup prices and display the prices of items to the screen. well we were given a second project which builds upon this program. basiclly we were supposed to design a main menu for the sales associate and we were to put the main menu in a loop to where it repeated until the program was exited. my problem is I have a secondary menu for the sales associate to add items that a customer purchased, however I always get a run time error that the string index is out of bounds. I will post a copy of the code so you can get an idea.

import java.util.Scanner;
import java.io.*;

public static void main(String[] args) throws IOException

//constant
final double taxRate = 0.08;

//variables
double shoes;
double tShirts;
double shorts;
double caps;
double jackets;
double prodAmt; // holds the cost without tax
double cost; // holds the cost
double tax; // holds the tax of the product
double totalCost; // holds the total cost of the product
String cust;
String custName;
String custName2;
String custAdd; // holds the customers street address
String custCity; // holds the customers city, state, and zip
String custEmail; // holds the customers email
String input; // holds the input from option 3
char answer; // reads the first character from input on option 3
int quantity; // holds the quantity of the product purchased
int number; // holds the number entered on main screen
int price; // holds the number entered for price lookup

shoes = 50.00; // tells the price of shoes
tShirts = 30.00; // tells the price of tshirts
shorts = 75.00; // tells the price of shorts
caps = 15.00; // tells the price of caps
jackets = 100.00; // tells the price of jackets

// sets the accumulator to 0
totalCost = 0.0;

/** the switch statements come from chapter 3 section 3.9

* the various math calculations came from chapter 2
*/


the problem is with the if statement, I've tried with a switch statement and it has the same problem however if I omit the if statement the loop works just fine. any ideas on what my problem is?

Please edit your post and wrap the code with code tags.

get a run time error that the string index is out of bounds.

Please post the full text of the error message that shows where the error happens and what the value of the index was.
